Automatic bag folding mechanism

The invention relates to an automatic bag folding mechanism. The automatic bag folding mechanism comprises a fixed support, and a bag film forming assembly and a folding assembly which are arranged onthe fixed support. The bag film forming assembly comprises a fixing mechanism for a bag body to be inserted therein, and a first power mechanism for driving the fixing mechanism to move up and down.Folding seams are arranged on the two sides of the fixing mechanism. The folding assembly comprises a left insertion board and a right insertion board which are located on the two sides of the fixingmechanism and matched with the folding seams. The left insertion board and the right insertion board can move forwards and backwards in the insertion direction of the folding seams under the effect ofa second power mechanism and a third power mechanism correspondingly. The automatic bag folding mechanism is simple in structure and can better fold a bag; and by means of a pressing mechanism of theautomatic bag folding mechan
